Delhi's Education Minister Atishi Singh declared that all elementary schools in the state would be closed until 10 November due to the rapidly declining air quality. The schools now have the opportunity to move their classes online for students in grades 6 through 12.
"As pollution levels continue to remain high, primary schools in Delhi will stay closed till 10th November. For Grade 6-12, schools are being given the option of shifting to online classes.," said Delhi Education Minister Atishi on social media platform X, formerly known as Twitter.
The air quality index worsened from 415 at 4 p.m. on Saturday to 460 at 7 a.m. on Sunday.
